S-99397A164 Length 8 mm Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding environments.
• Enhanced torque transmission and reduced cam-out thanks to the Torx Plus IP5 drive, ensuring secure fastening and minimizing tool wear.
• Reliable thread forming in plastics with the tri-lobe shank design, creating strong, vibration-resistant threads without pre-tapping.
• Optimized for plastic assemblies with a blunt tip and fully threaded design, preventing material cracking and ensuring consistent holding power.
• Streamlined installation process with compatibility for a standard No. 54 drill bit, reducing setup time and improving assembly accuracy.
• Broad industrial compliance meeting RoHS 3 and REACH regulations, ensuring safe use in global markets and sensitive applications.
• Secure and flush fastening with the standard pan head profile, providing a low-profile finish that resists snagging.

Professional Applications & Engineering Value

This M1.59 x 8mm TRS tapping screw is engineered to address common challenges in plastic assembly, such as material stress and thread stripping. The zinc-plated steel material offers excellent durability against environmental factors, while the thread forming TRS design with a tri-lobe shank displaces plastic material to form precise, high-strength threads without generating chips. This eliminates the need for additional inserts and reduces assembly steps. The Torx Plus IP5 drive ensures maximum torque transfer, minimizing the risk of screw head damage during high-speed automation. Ideal for electronics enclosures, automotive trim, and consumer goods, this screw provides a reliable, vibration-resistant fastening solution that maintains integrity under dynamic loads.

Specification Summary & Compliance

This metric screw features a M1.59 diameter with an approximate thread pitch of 0.6 mm and fully threaded right-hand thread design. It adheres to standard dimensional tolerances for precision fit. The product is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and suitable for use in environmentally conscious industries.
